The winner of Sunday's AFC South showdown in Indianapolis between the Colts and Tennessee Titans keeps its division title hopes alive while the loser falls behind in a crowded wild-card race. Indianapolis and Tennessee sit one game behind South leader Houston, which hosts New England on Sunday, and are two of four 6-5 teams fighting for a wild-card spot in the AFC.

The Titans have surged into the playoff picture by scoring 77 points in home victories over Kansas City and Jacksonville sandwiched around their bye week. Tennessee running back Derrick Henry has led the charge with 347 rushing yards and four touchdowns in the two games, leaving him nine yards shy of his second straight 1,000-yard season. "Late in the year, I feel like that's ultimately when he's at his best," Titans safety Kevin Byard told reporters about Henry. "Guys are banged up. Guys don't want to tackle this man in the fourth quarter. I'm glad I don't have to because he's on my team. ..." The Colts have won three straight meetings after a 19-17 victory at Tennessee in Week 2 behind three touchdown passes by Jacoby Brissett.

ABOUT THE TITANS (6-5): Ryan Tannehill is 4-2 since taking over at quarterback from Marcus Mariota with 10 touchdown passes against four interceptions. Wideout A.J. Brown had four catches for 135 yards and a touchdown in last week's 42-20 victory over Jacksonville and leads AFC rookies with 581 receiving yards. Linebacker Jaylen Brown had a career-high 15 tackles last week while Kenny Vaccaro is the only safety in the league with a sack in each of the last seven seasons after recording one versus Jacksonville.

ABOUT THE COLTS (6-5): Running back Jonathan Williams has filled in admirably for the injured Marlon Mack (hand) as he tries for his third straight 100-yard game. Brissett has 15 touchdown passes and four interceptions this season but has thrown for only one score in the last four contests. Wideout T.Y. Hilton (team highs of 378 receiving yards and five TDs) has only five catches for 72 yards in his last two games.
